Abstract:
Methods provided may generally include sending a BS of a first RAT a request message indicating a set of MIMO resources to reallocate; during a scan duration, communicating with the BS of the first RAT using non-reallocated MIMO resources and communicating with a BS of a second RAT using reallocated MIMO resources; and during a normal duration, communicating with the BS of the first RAT using the reallocated and non-reallocated MIMO resources. Apparatus provided may generally include logic for receiving a request message indicating a set of MIMO resources of the MS to reallocate; logic for, during a scan duration, communicating with the MS in a first transmission mode assuming the use of only non-reallocated MIMO resources by the MS; and logic for, during a normal duration, communicating with the MS in a second transmission mode assuming the use of the reallocated and non-reallocated MIMO resources by the MS.
Abstract:
A method and apparatus for adjusting and offsetting a power level of uplink transmissions from user equipment in a wireless communication system. In an aspect of the disclosure, a handoff from a source base station to a target base station includes the target base station determining a suitable power offset value and communicating this offset to the source base station. The source base station transmits a handover instruction including the offset to the user equipment (UE), and the UE transmits a synchronization code. The target base station then calculates a further power correction and transmits the correction with an acknowledgment of the synchronization code. The UE then sets the power for future transmissions based in part on the offset and correction values.
Abstract:
A method and apparatus enable high-speed downlink data transmissions to continue while a baton handover is in progress. In an aspect of the disclosure, a method of wireless communication includes switching an uplink from a source cell to a target cell while maintaining a downlink with the source cell, and transmitting over the uplink to the target cell at least one metric of quality of the downlink. In one example, the metric of quality may be a CQI. In another example, the metric of quality may be a HARQ ACK/NACK. The metric of quality of the downlink may be transmitted from the target cell to the source cell, directly or by way of a radio network controller.
Abstract:
Methods, systems, and devices are described for concurrently performing handoff-related measurements for neighbor cells using multiple input multiple output (MIMO) antenna resources. In one example, a mobile device is in communication with a serving cell. Handoff-related measurements of first wireless signals from a first neighbor cell are performed. The first wireless signals are received at first MIMO antenna resources of a device. Handoff-related measurements of second wireless signals from a second neighbor cell are performed, as well. The second wireless signals are received at second MIMO antenna resources concurrently with the first wireless signals received at the first MIMO antenna resources. The first handoff-related measurements and the second handoff-related measurements may be performed during a scan interval. A type of handoff-related measurement to perform may be determined based on a determined length of the scan interval.
Abstract:
Aspects of the present disclosure provide power efficient methods to track an emergency call. A mobile station may take Location Base Service (LBS) measurements during a low power state and may report the measurements to a serving base station. The serving base station may report the measurements to a network control and management system (NCMS) to track the emergency call.
Abstract:
A method of wireless communication in a dual subscriber identification module (SIM) terminal includes transmitting a first synchronization message from a first module associated with a first SIM. The method also includes receiving a first acknowledgment (ACK) message on a fast physical access channel (FPACH) in response to the first synchronization message. The method further includes sharing timing information included in the first ACK between the first module and a second module.
Abstract:
Certain embodiments of the present disclosure allow a mobile station to activate a sleep mode in order to reduce power consumption when the residual battery capacity is low. Certain embodiments of the present disclosure also provide techniques for adaptive power saving applied during an idle mode operation.
Abstract:
A method for facilitating dynamic service-based system selection and determination may be implemented by a communications device. The method may include presenting system selection options to a user based on information that is received about Network Access Providers (NAPs) and Network Service Providers (NSPs). The method may also include receiving user input about the system selection options. The user may be permitted to provide input about specific services offered by specific NSPs. The method may also include determining user preferences regarding system selection based on the user input. The method may also include creating a preferred roaming list (PRL) based on the user preferences. The method may further include using the PRL to scan for available networks and channels and to find serving systems.
Abstract:
Methods and apparatus for configuring and scheduling paging intervals for a mobile station (MS) having multiple subscriber identity modules (SIMs) to be aligned are provided. The MS having multiple SIMs may operate in a network via a particular radio access technology (RAT), such as Code Division Multiple Access (CDMA) EVDO (Evolution-Data Optimized). By having aligned paging intervals, the MS may wake up only once during the paging cycles for the various SIMs rather than waking up multiple times, thereby reducing power consumption of the MS during idle mode compared to a conventional MS with multiple SIMs.
Abstract:
In accordance with a method for implementing Short Message Service (SMS) in a WiMAX network, a mobile station may send a mobile station SMS request message to a base station. The mobile station SMS request message may include mobile-originated SMS data. In response, the base station may send a base station SMS response message back to the mobile station. For mobile-terminated SMS data, the base station may send a base station SMS request message to the mobile station. The base station SMS request message may include the mobile-terminated SMS data. In response, the mobile station may send a mobile station SMS response message to the base station. Ranging procedures and medium access control (MAC) management messages may be used to allocate bandwidth for the various messages.
